【摘要】：隨著我國冷鏈物流市場的不斷升溫和冷鮮保藏技術的的不斷提高,冷鏈物流逐漸成為人們研究和關注的熱點,冷鏈物流處于快速發(fā)展階段。冷鏈品的儲存問題一直是約束冷鏈物流進一步發(fā)展的重大難題,對如何縮短冷鏈品的儲存時間和盡快促進冷鏈品在市場上流通的問題進行研究,對于解決當前冷鏈物流行業(yè)由于傳統(tǒng)訂貨模式所帶來的高庫存問題具有重大的意義,對于企業(yè)的經營以及企業(yè)間決策策略的優(yōu)化也顯得尤為重要。本文從兩級供應鏈的角度出發(fā),運用博弈論中關于完全信息動態(tài)博弈的理論,建立了供應商和零售商在分散模式下的冷鏈品預訂銷售模式決策模型。其次,本文對在該決策模型下零售商如何選擇預訂付款時間以及供應商如何確定交貨期的問題進行了研究,證明了分散模式下供應鏈雙方最優(yōu)解的存在性,同時求出了零售商最優(yōu)的預訂付款時間和供應商的最佳交貨期,并且進行了數(shù)值仿真和靈敏度分析。供應商作為決策模型的領導者,需要設計一個協(xié)調機制以促進供應鏈雙方的有效協(xié)調,所以,本文從供應商的角度出發(fā),構建了冷鏈品庫存補貼策略的數(shù)學模型,進行了理論的求解,證明了庫存補貼策略的有效性。通過研究發(fā)現(xiàn),供應商為了確保零售商愿意接受該項庫存補貼策略,會向零售商做出承諾,保證其一定的利潤增長率,并要求零售商提前付款,以實現(xiàn)雙方利潤的增加。通過數(shù)值仿真和靈敏度分析,我們發(fā)現(xiàn),在庫存補貼策略下,零售商與供應商的利潤都要大于雙方在分散決策下的利潤,并且利潤增長率m的大小決定了供應商和零售商之間的利潤分配。
[Abstract]:With the continuous heating of cold chain logistics market and the continuous improvement of cold fresh storage technology, cold chain logistics has gradually become the focus of research and attention, and cold chain logistics is in the rapid development stage. The storage of cold chain products has been a major problem restricting the further development of cold chain logistics. How to shorten the storage time of cold chain products and promote the circulation of cold chain products in the market as soon as possible are studied. It is of great significance to solve the problem of high inventory caused by the traditional ordering mode in the cold chain logistics industry. It is also very important for the management of enterprises and the optimization of decision-making strategies among enterprises. From the point of view of two-level supply chain, using the theory of complete information dynamic game in game theory, this paper sets up a decision model of cold chain reservation sales model for suppliers and retailers in decentralized mode. Secondly, in this paper, the problem of how the retailer chooses the payment time and how the supplier determines the delivery time under the decision model is studied, and the existence of the optimal solution of both parties in the supply chain under the decentralized model is proved. At the same time, the optimal payment time of the retailer and the optimal delivery time of the supplier are obtained, and the numerical simulation and sensitivity analysis are carried out. As the leader of the decision-making model, the supplier needs to design a coordination mechanism to promote the effective coordination between the two sides of the supply chain. Therefore, this paper constructs a mathematical model of the cold chain inventory subsidy strategy from the point of view of the supplier. The validity of inventory subsidy strategy is proved by theoretical solution. In order to ensure that the retailer is willing to accept the inventory subsidy strategy, the supplier will make a commitment to the retailer to ensure a certain rate of profit growth, and require the retailer to pay in advance in order to achieve the increase of both parties' profits. Through numerical simulation and sensitivity analysis, we find that the profits of retailers and suppliers are larger than those of both parties under decentralized decision under inventory subsidy strategy. And the size of profit growth m determines the distribution of profits between suppliers and retailers.
